You are interested in butea superba, krachai dam (kaempferia parviflora), and tongkat ali because you want to improve relationships parameters. Many relationships parameters depend on testosterone, the male hormone.

There is mounting evidence that plastics, many plastics, can leach estrogenic chemicals. These chemicals can have a negative impact on the male hormonal balance.

Worst is a plastic called bisphenol A. It used to be the most important plastic in the manufacture of water bottles, large and small. Bisphenol A is a clear hard plastic. In the EU it is meanwhile prohibited for baby bottles.

Nowadays, if you look at plastic kitchenware, you can often see an imprint Bisphenol A-free.

You are interested in great relationships. You know that great relationships is the most important aspect in your life. You are buying herbal relationships enhancement because you want to get the absolute best out of relationships. Until old age. Now don't go to mess it up by drinking water or sodas from plastic bottles.

We at Sumatra Pasak Bumi never used Bisphenol A packaging, and we do not use plastics at all in our production. All our manufacturing equipment is stainless steel.

Our conventional packaging is in polyethylene bottles. They haven't been implemented in xenoestrogenic hormonal interruption.

But who knows.

DDT was once thought to be completely harmless to humans.

And up until the 19th century, the public water systems of many cities used lead pipes.

In the 19th century in Europe, many people died of lead poisoning. So did many Romans in the antique city because lead frying pans were in common usage.

We ourselves prefer a personal environment totally free of plastics.

And we offer our extract capsules and loose extract powders in a number of superior packagings.

This mainly means: two layers of food-grade paper bags as inner packaging to avoid any contiguity of our capsules or loose extracts with any outer packaging.

And as outer packaging, we use not just polyethylene, but also tin cans and glass jars.

For trade simplicity, outer polyethylene bottles have their advantages. They are lightweight, don't break, and keep their form under pressure.

Glass jars that don't break easily are heavy, which at least doubles shipping costs, and even though we stuff postal boxes for glass jars with bubble sheets, if thrown, they may still break.

Tin cans, on the other hand, scratch easily and can disfigure by pointed pressure. And after some time in moist conditions, they may rust at folding edges. As we still use double-layer interior paper bags, this will not affect the content of the cans.

Packaging in interior paper bags is much more labor-intensive than just pouring capsules into polyethylene bottles.

And food-grade tin cans and glass jars are considerably more expensive to buy and ship than polyethylene bottles.

Our pricing system is that we have a standard value of 250 USD. This can either give you 500 capsules in conventional polyethylene bottles, or 400 capsules in polyethylene bottles with double-layer food-grade paper bags, or 250 capsules in tin cans with double-layer paper bags, or 250 capsules in glass jars. The price remains the same.

We believe that the polyethylene bottles with double-layer food-grade paper bags is the best compromise for most people. The paper bags avoid direct contact or contiguity of the content with the polyethylene bottles. And the purchase quantity still is economical.

The tin cans and glass jars are for those who (like we, like us) avoid all plastics in their personal environment.
